I am trying to read a certificate that I got from a timestamping service.
The certificate reads into IE 5 fine.

The certificate reads into a Java 1.1.7 class fine. The critical line in 1.1.7
is:
sun.security.x509.X509Cert cert = new sun.security.x509.X509Cert(bytes);

In Java 1.2 and 1.3, sun.security.x509.X509Cert is depreciated. So I use the
new
classes. The critical line is:
java.security.cert.X509Certificate cert = (java.security.cert.X509Certificate)
cf.generateCertificate(bais);
This line throws an exception:
java.security.cert.CertificateParsingException: java.io.IOException:
java.io.IOException: Invalid encoding of AuthorityKeyIdentifierExtension.

I also tried the keytool -import function on the certificate file and it simply
says
Not a X.509 Certificate

Here's the certificate in question:
